Detailed Explanation of Flower Disorders and Their Causes

Flower disorders: 1. The base of the flower's labellum (lip) turns red. Cause: Damage from low temperatures. 2. The flower's labellum turns red or an abnormal red, and withers prematurely before maturing. Cause: The flower has been pollinated or the pollinia have already dropped off. 3. The outer edge of the flower's labellum becomes discolored and dried up, and some flowers are deformed. Cause: The flowers have been exposed to direct strong light for too long. 4. The flower withers before maturing, and the ovary area turns yellow or pink. Cause: Ethylene pollution. 5. The calyx withers and becomes discolored first, and the veins of the petals become noticeably thinner. Cause: Ethylene pollution. 6. Flowers are occasionally deformed. Cause: During the flower bud differentiation stage, damage from chemicals, too great a temperature difference, or excessive use of "bud-forcing hormones." 7. Every time they bloomthe flowersare deformed in the same way. Cause: Possibly a genetic factor. If the deformity is beautiful, then "things are precious for being rare." (Xue Congxian)
